YARN GUIDE AND CLEARER.

Specification of Letters Patent.

Application filed July 11, 1912.

To all whom it may concern:

Be it known that I, WILLIAM T. C. HAR- RiNe'roN, a citizen of the UnitedStates, residing at Fall River, in the county of Bristol, State ofMassachusetts, have invented a certain new and useful Improvement inYarn Guides and Clearers, of which the following is a specification,reference being had therein to the accompanying drawings.

The invention consists in an improved yarn-guide and clearer for use inspoolers and other like machines.

The invention in its preferred form is illustrated in the drawings.

In the latter, Figure 1 shows in front elevation a yarn-guide andclearer embodying the invention, and a portion of the supporting-rod forthe same. Fig. 2 is a view looking from the right in Fig. 1. Fig. 3 is atop view of the parts shown in Figs. 1 and 2.

Having reference to the drawings,at 1 is represented a portion of thehorizontal supporting-rod employed in a spooler for the support of oneor more yarn-guides and clearers. This rod usually in practice hastraversing movement communicated to the same for the purpose of properlydistributing upon the receiving spool or spools the yarn or yarns whichare being wound thereon. At 2 is a block or bracket which is mountedupon the rod 1, the said block or bracket having a socket madetransversely therethrough, of a size to receive and lit thesupporting-rod, the said socket being split, and a screw 4 beingprovided to draw the sides of the socket toward each other to clamp theblock or bracket tightly upon the supporting-rod. After loosening thescrew 4. the block or bracket may be shifted along the rod or be turnedaround the same. By the tightening of the screw 4 the block or bracketmay be secured upon the rod in the required position of axial or angularadjustment. At 5 and 6 are the blades of my yarn-guide and clearer, 5and 6 bemg the working edges of the said blades. The latter extend inparallel directions from an end-piece 7 The blades and end-piece mayconveniently be made integral, of one piece of sheet-metal, cut to therequired shape for the blades and end-piece and bent into U- shape, theend-piece forming the bend or bight of the U. The blade member isattached to the block or bracket 2 by means of a screw 8, the latterpassing through a hole in the end-piece 7 and entering a threaded holetapped in the block or bracket.

On tightening up this screw the end-piece is clamped against one side ofthe block or bracket by the flanged head of the screw. The upper edge ofthe blade 5 and the under edge of the blade 6 are the working edgesthereof. The working edges of the two blades lap past each other, sothat a yarn a passing through the guide and clearer will be supported bythe edge 5" of the blade 5 but deflected downward by the edge (3 of theopposite blade 6. Consequently as the yarn is drawn forward to thereceiving spool and wound upon the latter by the rotation thereof itstension causes it to bear against the edges of both blades. The bladesare separated somewhat transversely, and the space above the blade 5,and more particularly that beneath the blade 6, are entirely open andunobstructed, there being nothing between the two blades or at the rearof blade 5 and beneath blade 6 to constitute an obstruction or catchlint or other particles detached from the yarn. The blades may beangularly adjusted around the screw 5 so as to set the working edges 5-and 6 higher or lower with respect to each other. Thus the said bladesmay be set or adjusted so as to bend or deflect the yarn more or lesssharply around their working edges. One changed adjustment of the bladesis indicated in dotted lines in the drawings. By this angular adjustmentof the blades about an axis parallel with the latter the clearing actionof the device may be regulated, and also the tension of the yarn inbeing wound on the receiving spool.

My device acts to scrape and detach impurities, etc., from the yarnbeing operated upon, without any tendency to positively grip and holdthe yarn. onsequently it will not positively hold the yarn so as tooccasion breakage of the latter when a slug or piecing presents itself.A slug or piecing will pass both working edges without being caught andheld.

I claim as my invention 1. In a yarn-guide and clearer, in com bination,a supporting-bracket, blades having the working edges thereof indifferentplanes parallel with each other and facing in oppositedirections, said blades adjustable in unison around a common axis whichis parallel with the blades to vary the angle of deflection of the yarnin passing the blades.

2. In a yarn-guide and clearer, in combination, a 'supporting-bracket, apair of blades and connecting end-piece, and means for connecting saidend-piece to the bracket With capacity for angular adjustment to varythe angle of deflection of the yarn in passing the Working edges of theblades, the said edges facing oppositely.

3. In a yarn-guide and clearer, in combination, a supporting-bracket,upper and lower blades 5, 6, having the Working edges 5 6*, thereoffaced in opposite directions, a connecting end-piece 7 integral With.said blades, and means for pivotally clamping said end-piece t0 thebracket whereby the blades may be angularly adjusted to vary the angleof deflection of the yarn in passing the said Working edges.

In testimony whereof I afiix my signature in presence of tWo Witnesses.
